So in an interesting experiment with this photo I managed to create a giant soft box by stretching a large piece of white cloth which I had bought as a white background (but proved pretty useless for that) out in front of my SB700 flash (with diffuser attached). It created a huge area of diffuse light which was controllable through adjustment of the cloth - covering it folding it etc. The effect was somewhat like window light albeit on a dull sort of day. Anyway I was pleased with the results as it gave the kind of look I was after. The only problem is it didn't look like a window so I couldn't have it in the shot although I suppose that could be another thing to work on. At about £86 with both stands and a 3x6m sheet from Amazon it's actually a lot cheaper than most decent brand medium soft boxes let alone anything of a similar size and it's also easy to dissassemble and put away even coming with it's own bag. I'll put the Amazon links at the bottom. Note I wouldn't recommend it as a backdrop (unless you're some kind of Ninja with an iron).
As with nearly all of my photos retouching was in Adobe Photoshop CS6 and Nik Software Color Effex Pro 4. I also quite like the monochrome versions which I can post if anyone is interested.
